What would you do if you found a photo of your 12-year-old son cutting himself on his Instagram account along with a caption that said he planned to kill himself on his 13th birthday, just days away?

That’s just what happened to Karen, Noah’s mom. Her son is already in therapy for help coping with bullying. But after this new threat, Karen is desperate to help her son. “I have been doing my very best. But he is in pain. I can't do this alone,” she writes.

So, on Monday, she launched the Letters for Noah Facebook page in the hopes of starting a viral letter-writing campaign aimed at showing Noah that people really care and that life is worth living. She wants to get as many letters to Noah as possible before he turns 13 on Feb. 8.

You can send letters to Noah, P.O. Box 444, Simpsonville, Maryland 21150, or you can words of encouragement on the Facebook page. And spread the word: So far the Facebook page is at 3,000+ likes, and his mom’s post has been shared more than 1,300 times.
